Only unquote --variable when it appears quoted

The change to unquote values in the --variable output broke users that
had shell special characters in the variable. Instead, only unquote if
the value starts with " or '. A larger fix to do a full unquote, split
and escaping like --cflags/--libs is possible, but that might break the
old semantics even further.

Add a new function, parse_package_variable(), to handle that logic.
